This is kind of... Well, good news, I suppose? It depends on where you allegiances lie, but it seems like Ubuntu is warming up to the idea of using Qt to develop applications. It's no secret that Qt is a far more advanced development framework than Gtk+, so it only makes sense for Ubuntu - a GNOME/Gtk+ distribution - is looking at it.

Considering Nokia loosened the licensing terms when they purchased Trolltech, plus their push for Meego as an open platform for phones/tablets, which QT is their main contribution, I think it is a safe assumption that QT will remain LGPL.

You are attempting to spread fear, without a slightest bit of evidence, that Nokia may close the platform, despite already opened it up further than it was before.

That's so true, wasn't Nokia the one who oposed to ogg video as a HTML5 standar? and the one who is know using patents to sue the competence? What does that speak to you? oh and ain't Nokia being acussed of human righs violations an opression?

But even if they preferred to make it proprietary and never released the code, the open source community would still develop an LGPL Qt 4.7.

As it is, not only would the comunity have that option the last Qt release would become released under a BSD license making it possible for anyone to make their own proprietary version if they so wishes.

So even if Nokia would want to relicense, they would have to ask permission from every outside contributor or rewrite every outside contribution themselves. This makes the probability of a license change pretty low.
